“…Glycocalyx-mediated flow sensing will thus be converted into two major routes leading either to production of nitric oxide (NO) or to reorganization of the cytoskeleton through remodeling of both intercellular and extracellular matrix-linked junctions (Tarbell and Pahakis, 2006). The glycocalyx is present in the developing vascular network (Henry et al, 1995), but its role during embryogenesis remains to be explored.…”

Throughout morphogenesis, cells experience intracellular tensile and contractile forces on microscopic scales. Cells also experience extracellular forces, such as static forces mediated by the extracellular matrix and forces resulting from microscopic fluid flow. Although the biological ramifications of static forces have received much attention, little is known about the roles of fluid flows and forces during embryogenesis. Here, we focus on the microfluidic forces generated by cilia-driven fluid flow and heart-driven hemodynamics, as well as on the signaling pathways involved in flow sensing. We discuss recent studies that describe the functions and the biomechanical features of these fluid flows. These insights suggest that biological flow determines many aspects of cell behavior and identity through a specific set of physical stimuli and signaling pathways.

“…Nevertheless, despite the importance that carbohydrates play as markers of both cell heterogeneity and functional specializations in several biological systems (Schuster et al 1986;Fukuda 2000), reports on glycan components of the CAM are lacking. Only one study, to our knowledge, has focused on glycoconjugate expression at the very early stages of the CAM formation, when differentiation of the distinct cell types has not yet been achieved (Henry et al 1995). In this context, the objective of our study was to visualize carbohydrate expression in the chick CAM during embryonic development and contribute to characterize further the individual cell types present in the CAM epithelia.…”

Widespread interest has focused on the research of the chorioallantoic membrane (CAM) and its functional contribution to gaseous exchange, calcium reabsorption, water and electrolyte transport during chick embryogenesis. Nevertheless, very little information is available on the glycoconjugate components of this extra-embryonic structure. In the present study, we investigated by lectin histochemistry, the glycosylation pattern expressed in the CAM epithelia during embryonic development. Occurrence of sialic acid-associated glycoproteins was detailed by either specific lectins, which discriminate alpha2,3 and alpha2,6 sialoderivatives, or sialidase digestion combined with appropriate lectins to identify the sialic acid acceptor sugars. Lectin affinities proved to depend greatly on differentiation of the CAM epithelia which showed highest expression of binding sites during the second half of incubation up to hatching. Differences emerged between the chorionic and the allantoic epithelium, regarding qualitative, quantitative and temporal expression of sugar moieties. A cell type-specific distribution of glycocomponents was found in the chorionic epithelium where lectin binding sites were specifically located in the villus cavity cells. In the allantoic epithelium, high and heterogeneous occurrence of sialoglycoconjugates as well as specific presence of fucose residues were evidenced mostly in the granule cells. We conclude from these findings that various glycoconjugates in the CAM could participate in different physiological functions characteristic of the chorionic and the allantoic epithelium.

Glycoconjugate expression in the chick embryonic chorioallantoic membrane: Comparisons of the chorionic ectoderm and allantoic endoderm

Abstract: That the ultrastructurally similar ectoderm and endoderm of the CAM display functional differences conforms to the hypothesis that differential expression of glycoconjugate microdomains likely contributes to such functional specialization.
